Comprehensively accounting for the effect of giant CCN in cloud activation parameterizations

Abstract:

Large cloud condensation nuclei (CCN) (e.g., aged dust particles and seasalt) cannot attain their equilibrium size during the typical timescale of cloud droplet activation. Cloud activation parameterizations applied to aerosol with a large fraction of large CCN often do not account for this limitation adequately and can give biased predictions of cloud droplet number concentrations (CDNC). Here we present a simple approach to address this problem that can easily be incorporated into cloud act...
